Device mapper failed to open temporary keystore device

Device mapper failed to open temporary keystore device

[Murilo Opsfelder Araújo]

Hello, everyone.

Right after I enter my passphrase to unlock my cryptsetup partition,
it displays the following error and asks for cryptsetup password again
(it got stuck on this loop).

This issue was introduced in next-20150413.  next-20150410 is working just fine.

Any hint on how to debug this?

Unlocking the disk /dev/disk/by-uuid/<uuid> (sda5_crypt)
Enter passphrase: *****

git diff next-20150410^..next-20150413 drivers/md/dm-crypt.c points to
this commit as the nly dm-crpt.c change:
https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=for-next&id=5977907937afa2b5584a874d44ba6c0f56aeaa9c

Which appears unrelated given your "crypt: Error allocating crypto tfm"
error.

But any chance you can try reverting that commit from next-20150413 and
re-test just to be absolutely sure?

There are also some crypto changes that could very easily be the cause
of your problem (cc'ing Herbert), e.g.:

$ git diff next-20150410^..next-20150413 -- crypto | diffstat

My guess is that you guys need this patch:

commit 34c9a0ffc75ad25b6a60f61e27c4a4b1189b8085
Author: Herbert Xu <herbert@gondor.apana.org.au>
Date:   Thu Apr 16 11:07:13 2015 +0800

    crypto: fix broken crypto_register_instance() module handling

Hello, Herbert.

Sorry for my ignorance but which tree and branch does this commit come from?

I tried next-20150422 (that contained Herbert's patch) and it worked just fine.

Thank you, guys.

Hello, Mike.

I've reverted that commit from both next-20150413 and next-20150415.
In both cases, I got the same error, no success.
